PAPER-CLIP.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed October 28, 1919. Serial No. 333,988.

To all whom it may concern:

Be it known that I, JOSEPH J. OBRIEN, a citizen of the United States ofAmerica, residing at Springfield, in the county of Hampden and State ofMassachusetts, have invented certain new and useful Improvements inPaper-Clips, of which the following is a specification.

This invention relates to improvements in paper clips and is directed toa paper clip having interfitting loops providing paper gripping jaws,the terminal of the, inner loop being extended cross-wise to provide athumb engageable bar, whereby the two loops or jaws may be separated tofacilitate ready insertion of paper between the jaws, and to providemeans whereby an index or memorandum card may be attached to the paperor record sheet, in such manner that it will project edge-wise of thepaper, so that the memorandum or index card will stand out from thepaper, thus permitting easy inspection when the paper is arranged in apile or stack, or also permitting easy removal of the card from thepaper.

Another feature of the invention is that the terminals of the clip aredeflected so that they will have biting engagement with the paper in oneposition, or stand out from the paper in the other position, to afl'ordeasy insertion of a card between the terminal and the paper to which thejaws of the clip are connected- Another feature of the invention is thatthe laterally deflected terminal of the inner jaw, indents the paperalong a line different from that of the parallel bars of-the jaws, sothat increased resistance is offered by the clip to frictionaldisplacement or slid- %till another feature of the invention is theprovision of a clip which can be manufactured at less cost, by providingmeans whereby the wire of which it is composed may be initially graspedby the forming dies, instead of forced between shaped dies.

With the above and other objects in view the invention consists ofcertain new and useful constructions, combinations and arapplied to anumber of sheets of paper, and

a card held by the clip against the paper.

Referring to the accompanying drawings A designates the clip which isformed with parallel bars B and C, which are connected to each other bythe U-shaped portion D..

A third bar E is connected to the bar C, by the U-shaped portion F, andthis bar is connected to the fourth bar G by the U-shaped portion H. Thebars 0 and G lie contiguous to each other, and the bars B and E liecontiguous to each other. The U-shaped portions D and H arelongitudinally spaced from each other to provide a relatively wideclearance I, all of which features are old and well known.

The bar G is extended laterally across the s ace J between the opposingbars E which it is attached, while in the other' position it willproject against and have biting engagement with the paper or card, thusproviding increased resistance to detachment from the paper or card.

The other terminal L, ofthe clip, is also deflected outwardl to performa similar double function. in one position the terminal will projectfrom the paper or card to which it is attached, thus permitting theinsertion of a card between the terminal and the paper to which the clipis attached, while in the other position the terminal will projecttoward and have biting engagement with the paper or card.

By appl ing the thumb nail against the cross bar C the jaws formed bythe loops D and H, will be easily separated, when the clip is grasped bythe hand. When the clip is attached to the paper or cards it may beeasily removed by pressing the nail against the cross bar.

The bars B and C and the connecting portion D form a U shaped outer. jawand the bars G and E and the connecting portion H, the cross bar Kandthe bridge portion F form a C-shaped inner jaw, one being continuouswith the other. I

The cross bar K is disposed inwardly of the U shaped end or connectingbridge F a considerable distance and provides a clearance for a formingtool or the jaw of a gripping former, an arrangement which simplifiesthe manufacture of the clip, since the wire can be gripped between thejaws of a forming tool and then coiled upon the forming tool to form theclip.

Having described my invention I claim 1. A paper clip consisting of anouter loop, an inner loop continuous therewith, the inner and the outerloops providing paper gripping jaws, the terminal of the inner loopbeing disposed laterally of the loop and deflected slightly from theplane of the clip and the terminal of the outer loop being deflectedslightly from the plane of the clip.

2. A material holding clip consisting of an outer U shaped jaw and aninner C- shaped jaw connected to the U shaped jaw to provide barsparallel to the sides of the U shaped jaw and transverse portionsconnecting said bars to each other and spaced apart from each other andfrom the ends of the U shaped jaw.

3. A clip for paper and the like consisting of an outer jaw includingthe bars B and C and the connecting portion B and an inner jawconsisting of the bars E and Gconnected to each other by the bar portionH and to the bar G by the portion F and having a cross bar K disposedinwardly of the portion F, the portion H being disposed inwardly fromthe portion B and spaced from the cross bar K.
